Title: Production of ceramic sintered compact
Inventor: TOKUNAGA HIDEAKI
IPC: H01C7/10
Filed: 1994-11-07
Abstract: PURPOSE: To obtain a ceramic sintered compact, containing few holes in the interior, excellent in mechanical strength and hardly affected by the surrounding atmosphere by covering the surface of a ceramic compact in a part requiring the denseness with an inert substance and then baking the resultant compact. CONSTITUTION: An inorganic oxide such as ZnO or Al2 O3 is used as a raw material to produce a ceramic compact. The surface thereof in at least a part requiring the denseness is then covered with an inert substance. Methods for covering the ceramic compact with a platy metal or a metallic oxide, covering the surface of the part requiring the denseness with a paste of the metal or metallic oxide and covering the surface of the compact, etc., are used as a method for covering the surface thereof with the inert substance. The obtained ceramic compact is then sintered to afford this ceramic sintered compact. Thereby, since a low-melting substance in the part requiring the denseness in the compact in baking thereof can be prevented from evaporating, the ceramic sintered compact containing few holes in the interior can be obtained.

IPC: H04J3/06
Filed: 1988-10-28
Abstract: PURPOSE:To prevent the synchronizing step out of a multiframe due to the insertion/deserting of delay from occurring by holding a multiframe signal transiently by separating it from an input signal, and outputting it with a regulated phase. CONSTITUTION:The multiframe signal is separated from the input signal 1 at a separation circuit 11, and the multiframe signal is sent to a memory circuit 12, and also, the input signal other than the multiframe signal is sent to an insertion circuit 13. The memory circuit 12 holds the multiframe signal transiently, and outputs it with a prescribed phase, and sends it to a selection circuit 14, and also, sends it to a delay circuit 15, and sends the signal to the selection circuit 14 after inserting the delay of one frame. The selection circuit 14 selects either the output signal of the memory circuit 12 or that of the delay circuit 15 by a selection control signal generated from a comparison result at a phase comparison circuit 20, and outputs it to the insertion circuit 13. The insertion circuit 13 superposes the multiframe signal on the signal again, and sends it to a selection circuit 18 and a delay circuit 16.

Title: Large-quantity copying method
Inventor: KAWABATA HIDETOSHI
IPC: G03G15/16
Filed: 1986-11-14
Abstract: PURPOSE:To obtain a sharp image by irradiating a photosensitive body with light through copying paper while a toner image which is developed on the photosensitive body surface and converted in polarity is pressed and held by the transfer paper. CONSTITUTION:The photosensitive body 21 which is charged electrostatically in a 1st process is exposed to an image to form an electrostatic latent image and toner is stuck on this electrostatic image, which is developed as toner images 11 and 22. The photosensitive body 21 is charged electrostatically so as to invert the polarity of the toner image and then the transfer paper 10 is sent onto the surface of the photosensitive body, thereby pressing and holding the toner images on the transfer paper 10. The photosensitive body surface is radiated with light through the transfer paper in this state, and consequently the photosensitive body surface drops in potential except at the toner images. Then the toner images on the photosensitive body surface is transferred to the transfer paper and then an electrostatic latent image which is higher in potential than when the electrostatic latent image is formed by the image exposure remains on the photosensitive body surface. This electrostatic latent image is used to repeat a series of processes from development to transferring for a 2nd and succeeding times. Consequently, part of the toner image which is converted in polarity after development is prevented from scattering to a lower-potential paper owing to the potential difference and the sharp copy image is obtained.

IPC: H01L27/14
Filed: 1989-10-19
Abstract: PURPOSE:To prevent production of flicker of a reproduced picture by adopting a transparent border of picture elements at which leakage of information charge is predicted with respect to an incident light so as to make the information charge quantity for leakage-out and leakage-in for each picture element equal to each other. CONSTITUTION:A color separation filter 20 is split in the vertical direction along a channel separation region 2, a transparent region 21 is provided along the end of transfer electrodes 3, 4 to divide the charge in the horizontal direction. The information charge from each photodetector is read simultaneously from n-th and (n+1)th lines in an odd number field and from (n-1)th and n-th lines in an even number field. Moreover, signals from adjacent picture elements in the horizontal direction are added to obtain a luminance signal and a color signal is obtained from the difference of the signals. In this case, the information charges leaked from each picture element come all from a region corresponding to the region 21 and they are nearly equal to each other in terms of the quantity. Thus, the leaked charges in both odd and number fields are cancelled together. Thus, the reproduced picture with high resolution and less flicker is obtained.
